The second end 16 of the housing 12 includes an electrical conductor 24 attached thereto for the purpose of conducting electrical signals between the inventive charger 10 and the cell phone P to be charged. The free end of the electrical conductor 24 terminates into an electrical connector 26 for connecting to the cell phone P to be charged.
Referring now to FIG. 2 a charger circuit 30 is disposed within the housing 12 and is in electrical communication with the electrical contacts 20 and 22 disposed at the first end 14 of the housing 12 and the electrical conductor 24 attached at the second end 16 of the housing 12.
The battery charger 10 includes a visual indicator circuit 32 having at least one light source disposed in the housing 12. The visual indicator circuit 32 is operative to provide a visual indication to the user when an incoming call is detected.
The visual indicating circuit 32 is provided in electrical communication with an incoming call sensing circuit 34 disposed within the housing 12. The incoming call sensing circuit 34 operates to detect an incoming call signal to the cellular phone P and thereafter to produce and electrical signaling response to detecting the incoming call signal. The incoming call sensing circuit 34 is further operative to communicate the electrical signal produced in response to the incoming call signal to the visual indicator circuit 32 to cause the light source to illuminate accordingly. Preferably, the visual indicating circuit 32 causes the at least one light source to continue to illuminate after the incoming call has been detected and until the visual indicator circuit 32 has been reset.
In this matter, if a user of the inventive battery charger is not immediately alerted to the occurrence of an incoming call during the detection period, the continued illumination of the at least one light source provides a means of alerting the user that an incoming call has been received.
Preferably, the light source contained within the inventive battery charger 10 is a solid state device such as an LED although other light emitting devices may be utilized for such purpose illustratively including incandescent bulbs.
The visual indicator circuit 32 may include the capability to cause the light source to flash intermittently in response to receiving an incoming call signal from the incoming call circuit 34. This feature may add to the capability of the battery charger to alert the user of an incoming call while the call is being detected.
As shown in FIG. 1, the battery charger 10 may include a signal conditioning and activation circuit 36 disposed between the incoming call circuit 34 and the visual indicator circuit 32. The signal conditioning and the activation circuit 36 is operative to receive the incoming call signal for conditioning and thereafter transmitting an electrical signal to the visual indicator circuit 32 for activating the at least one light source. The signal conditioning and activation circuit 36 may illustratively be comprised of an amplifier circuit, rectification circuit, and a solid state switch for activating the visual indicator circuit 32.
As illustrated in FIGS. 2 and 3, a reset button 38 is preferably disposed on the housing 12 and placed in communication with the visual indicator circuit 32 as described above, the visual indicator circuit 32 may be designed to continuously illuminate the at least one light source upon detecting an incoming call signal until the visual indicator call circuit 32 is reset. Accordingly, the reset button 38 is provided on the battery charger housing 12 in a manner that allows a user to simply push the reset button 38 to reset the visual indicator circuit 32 as needed.
Referring now to FIG. 3, an alternative embodiment of the battery charger 10′ is illustrated in a block diagram, the alternative embodiment is operative to receive an incoming call signal from the cell phone P from an incoming call sensing circuit disposed within the cell phone P as opposed to having the incoming call sensing circuit disposed within the battery charger housing 12.
